I have to go through my scripts and my very bad memory for your questions so if 
anyone finds fault with my answers to sandra please dont hesistate :)

1)
DRM marks the necessary tapes to go offsite at that point I check them DRM 
marks the necessary tapes to go offsite at that point I check them out using a 
script that I run once a day

move drmedia * wherestate=mountable tostate=vault remove=bulk

2)
when you bring the tapes back they are usually expired via the DRM and when you 
bring the tapes back they are usually expired via the DRM and therefore become 
scratch tapes

3) 
I personally dont use the "reuse delay" feature but according to the manual 
this is for DR purposes as the 
data on the tape isnt deleted only the database is updated.  If you try and 
bring the tapes back in as scratch 
after they have after the data has been moved,expired,deleted off of the tape 
but before the reuse delay TSM should 
complain and you will have to wait till the 3 day time period is complete.  
Again I dont use this feature and so I am \
just relaying what is in the manual.
